If you’ve got a thing for Thumper, you’ll probably want to avoid Savenor’s Market (92 Kirkland Street, Cambridge) on October 7, from 3 to 4 pm. That’ll leave more room for the rest of us to enjoy the gourmet butcher shop’s latest installment in its Butcher Series of seminars: “Rabbit Tales.” The cost is $25; call 617.576.MEAT for reservations, which are limited.
